Nitroxtec High Pressure Desiccant Dryers (Heatless Type)
Ultra-Dry, Clean Air — Now Up to 300 Bar
Nitroxtec High Pressure Desiccant Dryers are specifically designed to deliver moisture-free compressed air at pressures ranging from 40 to 300 bar. Built on reliable adsorption drying principles, these systems use high-performance desiccants such as activated alumina, silica gel, or molecular sieve to achieve dew points as low as –40 °C or –70 °C—all without external heating.
Whether you’re supporting high-pressure laser cutting, PET bottling, or critical gas processes, Nitroxtec ensures uninterrupted drying with maximum reliability and minimal energy consumption.
What is a Desiccant?
A desiccant is a hygroscopic material that absorbs moisture from the air. In desiccant dryers, wet compressed air flows over materials like silica gel, molecular sieve, or activated alumina, which remove water vapor. As the desiccant becomes saturated, it must be regenerated to regain its drying capacity.
To enable continuous operation, the dryer system uses two towers:
-
One tower dries the incoming air
-
The other regenerates with a small amount of purge air from the dried outlet stream
Towers switch roles automatically based on a timed cycle—delivering reliable, high-pressure drying without interruption.

Working Principle
Moist air at high pressure is directed into one of two desiccant-filled towers, where it passes through adsorbent media and is dried to the required dew point. A small portion of the dried, high-pressure air is used to regenerate the desiccant in the alternate tower. Towers switch cyclically and automatically to provide continuous drying, with no external heat or electrical heaters needed.
